Operation: S.P.R.O.U.T./Transcript


  • This episode spoofed the 1966 film, Fantastic Voyage.
  • When they're trying to grapple onto Wallabee's brain, Abigail notes that it's small.
  • To emphasize his sickness, Wallabee turns green in the face and he tosses and turns and says, "I want to clean my room" and "I gotta remember to do my extra credit homework!" According to Kuki, this means the sprout is taking over.
  • Nigel wears the same suit as he did in Operation: S.A.T.U.R.N..
  • This episode marks the first appearance of Numbuh 4's mother, Liza Beetles and his younger brother, Joey.
